The new sae_password hostapd configuration parameter can now be used to set the SAE password instead of the previously used wpa_passphrase parameter. This allows shorter than 8 characters and longer than 63 characters long passwords to be used. In addition, this makes it possible to configure a BSS with both WPA-PSK and SAE enabled to use different passphrase/password based on which AKM is selected.
